In certain scenarios, a list view with DataAccessMode set to Server may show empty rows or operate slowly. This behavior is usually caused by exceptions thrown during data loading that are handled internally. Such situations can be diagnosed using the debugger (see What to do when the grid displays blank rows in Server Mode and ASPxGridView displays empty rows when bound via Server Mode).
It would be helpful if XAF writes these exceptions to the log automatically.

We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.
Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.
Starting with v18.1, we improved the XAF built-in diagnostics for errors occurring in Server Mode data sources. Now, server-side errors (intercepted via the ServerExceptionThrown event) are written to the application log. In addition, when the log level is set to 4 (Verbose), errors reported via the InconsistencyDetected event are also written to the log. While the latter event doesn't always indicate a problem, the error message may be helpful in researching the cause of performance issues.
